<p><p><span>My VHF/UHF power output of my FT100 is in the milliwatt range. Before totally going out the TX would give full output and the die. I have measured the DC voltages on the output and driver device and thye look reasonable. Does anyone know what the voltages should be when operating properly? I do not see any information like that in the Service Manual. The lower stage driver devices are under a metal shield so I can not easily measure the voltages on those devices. </span></p><p><span><br></span></p><p><span>The HF TX output power is normal. The VHF/UHF RX works fine. Problem is limited to the TX for 2 and 440 bands. I understand the output device for the VHF/UHF are not available any more. Are there substitute devi
ces?</span></p><p><span><br></span></p><p><span>Any help would be useful.</span></p><p><span><br></span></p><p><span>73,</span></p><p><span><br></span></p><p><span>Wes</span></p><p><span>WA5TKU</span></p></p>
